Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, and in particular to an auxiliary equipment for material handling in civil engineering construction of a flexible DC converter station. Background Technology

[0002] As a core component of flexible DC transmission systems, the civil construction of flexible DC converter stations involves multiple stages such as foundation pouring, structural masonry, and equipment installation. During the construction process, a large amount of bulk materials such as sand, gravel, and cement need to be transported. The efficiency and stability of material handling directly affect the overall construction progress and work quality. This utility model is an auxiliary equipment for material handling in the civil construction of flexible DC converter stations.

[0003] Existing material handling equipment for civil construction requires the use of tools such as shovels, scrapers, and rakes to scoop and scrape materials during unloading. When using tools to unload materials, the unloading volume depends entirely on the manual control of the operator, making it difficult to achieve uniform unloading. Utility Model Content

[0004] This utility model embodiment relates to an auxiliary equipment for material handling in civil construction of a flexible DC converter station, in order to solve the technical problems mentioned in the background art.

[0005] In a first aspect, this utility model provides an auxiliary material handling device for civil construction of a flexible DC converter station, specifically comprising: a frame; two movable wheels are installed on the frame, a support frame is welded to the lower end of the frame, a storage hopper is bolted to the upper end of the frame, the bottom surface of the storage hopper is set as an inclined surface, and a discharge port is provided at the front end of the storage hopper, two rotatable rotating plates are installed at the front end of the storage hopper, a connecting plate is connected between the two rotating plates, a swing plate is connected to the right end of the connecting plate by a pin, a control rod is installed on the left side of the storage hopper by a bearing, the front end of the control rod is fixedly connected to the swing plate, rotatable side plates are installed on both the left and right sides of the storage hopper, a sealing plate is bolted between the two side plates, and a turnbuckle is connected between the front end of the sealing plate and the two rotating plates.

[0006] Furthermore, a push frame is welded to the rear end of the frame, and a through hole is provided on the left side of the push frame. The control rod is located in the through hole on the push frame, and two handles are installed at the rear end of the push frame. The handle near the left side of the push frame is fixedly connected to the rear end of the control rod.

[0007] Furthermore, a push rod is welded onto the push frame, and a feed plate is bolted to the front side of the frame.

[0008] Furthermore, a limit bolt is installed between the sealing plate and the storage hopper.

[0009] Furthermore, control plates are bolted to both side plates, and tension springs are installed between the storage hopper and the control plates.

[0010] Furthermore, the handle near the left side of the pusher can be rotated on the pusher.

[0011] Furthermore, a mounting base is installed at the rear end of the support frame, a rotatable rotating base is installed on the mounting base, casters are installed on the rotating base, a support is installed on the mounting base, a gearbox is installed on the support, the output shaft of the gearbox is connected to the rotating shaft of the rotating base through a coupling, a reducer is installed on the gearbox, and a handwheel is installed on the input shaft of the reducer.

[0012] This utility model provides an auxiliary equipment for material handling during the civil construction of a flexible DC converter station, which has the following beneficial effects: The bottom surface of the storage hopper of this utility model is designed with an inclined surface, which uses gravity to allow the material to naturally converge to the discharge port at the front of the storage hopper. The operator can rotate the control rod by turning the handle near the left side of the push frame. The rotation of the control rod drives the swing plate to swing synchronously. The swing of the swing plate will pull the connecting plate to move. The connecting plate connects two rotating plates, which in turn drive the two rotating plates to rotate synchronously around the installation point. When the rotating plates rotate, the sealing plate is pulled up by the turnbuckle, so that the sealing plate opens upward and completes the opening of the discharge port. By controlling the rotation of the control handle, the rising height of the sealing plate can be adjusted to achieve different unloading rates.

[0013] In addition, this utility model drives the tilting seat to tilt by turning the handwheel, which is then decelerated by the reducer and powered by the gearbox, thus achieving the "landing-retracting" switching of the casters. On flat surfaces, the casters are landed and work with the moving wheels to form four-wheel movement. On uneven surfaces, the casters are retracted and supported only by the moving wheels and the support frame, preventing the casters from sinking into the depressions and improving the reliability of the equipment.

[0025] Please refer to Figures 1 to 7 Example 1: This utility model proposes an auxiliary material handling device for civil construction of a flexible DC converter station, comprising: a frame 1; two movable wheels 11 are installed on the frame 1; a support frame 12 is welded to the lower end of the frame 1; a storage hopper 2 is bolted to the upper end of the frame 1; the bottom surface of the storage hopper 2 is set as an inclined surface; and a discharge port 21 is provided at the front end of the storage hopper 2; two rotatable rotating plates 22 are installed at the front end of the storage hopper 2; a connecting plate 221 is connected between the two rotating plates 22; a swing plate 222 is connected to the right end of the connecting plate 221 by a pin; a control rod 223 is installed on the left side of the storage hopper 2 by a bearing; the front end of the control rod 223 is fixedly connected to the swing plate 222; rotatable side plates 23 are installed on both the left and right sides of the storage hopper 2; a sealing plate 231 is bolted between the two side plates 23; and a turnbuckle 2311 is connected between the front end of the sealing plate 231 and the two rotating plates 22.

[0026] In this embodiment of the utility model, a push frame 13 is welded to the rear end of the frame 1. A through hole is provided on the left side of the push frame 13. The control rod 223 is located in the through hole on the push frame 13. Two handles 131 are installed at the rear end of the push frame 13. The handle 131 near the left side of the push frame 13 is fixedly connected to the rear end of the control rod 223. The handle 131 near the left side of the push frame 13 can rotate on the push frame 13. Its function is: when the operator rotates the handle 131 near the left side of the push frame 13, it can drive the control rod 223 to rotate synchronously. Then, the opening and closing of the sealing plate 231 can be controlled by the control rod 223 to realize the opening and closing of the discharge port 21 and the adjustment of the discharge rate.

[0027] In this embodiment of the utility model, a push rod 14 is welded on the push frame 13, and a discharge plate 15 is installed on the front side of the frame 1 by bolts. Its function is: the push rod 14 provides an additional gripping part for the operator to adapt to the pushing needs of operators of different heights; the discharge plate 15 guides the material discharged from the discharge port 21 to prevent the material from scattering during unloading.

[0028] In this embodiment of the present invention, a limiting bolt 2312 is installed between the sealing plate 231 and the storage hopper 2. The function of the limiting bolt 2312 is to limit the movement range of the sealing plate 231.

[0029] In Example 2, based on Example 1, control plates 232 are bolted to both side plates 23. A tension spring 2321 is installed between the storage hopper 2 and the control plate 232. Its function is: the tension spring 2321 uses its own elastic tension to apply tension to the side plates 23 through the control plate 232, and can assist the sealing plate 231 to reset and close after it is opened.

[0030] In Example 3, based on Examples 1 and 2, a mounting base 121 is installed at the rear end of the support frame 12. A rotatable rotating base 122 is installed on the mounting base 121. A caster wheel 123 is installed on the rotating base 122. A support 124 is installed on the mounting base 121. A gearbox 125 is installed on the support 124. The output shaft of the gearbox 125 is connected to the rotating shaft of the rotating base 122 via a coupling. A reducer 126 is installed on the gearbox 125. A handwheel 1261 is installed on the input shaft of the reducer 126. Its function is: when the operator rotates the handwheel 1261, the torque is reduced and increased by the reducer 126 and then transmitted to the gearbox 125. The gearbox 125 drives the rotating base 122 to rotate around the mounting base 121 through the output shaft and the coupling, so that the caster wheel 123 can be placed on the ground or retracted. When placed on the ground, it works with the moving wheel 11 to improve the turning flexibility of the equipment. When retracted, the support frame 12 ensures the static stability of the equipment.

[0031] The working principle of this embodiment is as follows: During use, construction materials are first loaded into the storage hopper 2. The discharge port 21 is sealed by the sealing plate 231. The operator holds the two handles 131 on the push frame 13 with both hands and pushes the frame 1 with the push rod 14. At this time, the moving wheels 11 roll to move the entire equipment. On a flat surface, the handwheel 1261 can be turned, driving the reducer 126. The reducer 126 transmits power to the gearbox 125. The gearbox 125 drives the tilting seat 122 to rotate around the mounting base 121 through the output shaft and coupling, causing the casters 123 to land. The support 124 provides stable support for the gearbox 125. The cooperation of the moving wheels 11 and the casters 123 improves the mobility of the equipment. When the equipment reaches the designated unloading position, the support frame 12 supports the equipment to remain stationary and stable. If it is necessary to retract the casters 123... The handwheel 1261 can be rotated in the opposite direction by the wheel 123. Then, the operator rotates the handle 131 near the left side of the push frame 13. The handle 131 drives the control lever 223 to rotate. The front end of the control lever 223 drives the swing plate 222 to swing. The swing plate 222 pulls the connecting plate 221 to move through the pin shaft. The connecting plate 221 drives the two rotating plates 22 to rotate synchronously. The rotating plate 22 pulls the sealing plate 231 to rise through the turnbuckle 2311, so that the discharge port 21 opens. The material in the storage hopper 2 converges towards the discharge port 21 under the gravity of the inclined bottom surface. After being guided by the discharge plate 15, it falls accurately to the target position. During the unloading process, the opening and closing angle of the rotating plate 22 can be controlled by adjusting the rotation amplitude of the handle 131, thereby adjusting the discharge rate. After the unloading is completed, the handle 131 is released. Under the tension of the tension spring 2321, the sealing plate 231 returns to its original position and closes.
